Structural Steel Applications

Our Purlin Fasteners are designed for predominately steel applications up to 1/4" thick. The fastener has 24 threads per inch which makes for easier driving. The drill point is also wider than the screw itself which allows thick metal to be drilled and chips to be cleared before the threads tap into the metal.
